Ive just been given an iRoast2 and have dutifully got myself the CS starter pack. Ive read about first cracks and rolling FCs and rolling second crackss, and how I should note temperatures, times, colour and actual taste. Ive done a couple of roasts on preset 1 and preset 2, and have written down FC and RFC (I presume) times.
But in truth, all Ive really done is let it run until the beans look about the right colour.
There are so many variables - bean, temp, time and temp profile. I could play around for the next couple of years changing one at a time and see what I get in the cup. But are there any principles to follow to make it simpler? At least with learning to make the coffee there was the 30s/60ml, and visual warm honey vs mousetail clues, and tasting right there and then, to gauge progress.
For example, Ive always had to cut the roast at 7 or 7.30 minutes, rather than the 9 and 11 on the presets. Is that bad? And with the roar of the iRoast, I dont know if Im hearing a RFC or a second crack. And does it matter?
